Claims.

This invention relates to apparatus for lling capsules with powder and the like.

A primary object of the invention is to provide an apparatus that will permit the simultaneous 5 filling of a number of capsuleswith powder and the like.

Another object is to provide such an apparatus that will readily hold a number of capsules in position for filling.

A further object is to provide such an apparatus that will hold the filled capsules in position for capping the same.

A still further object is to provide such an apparatus that is simple and rugged in construction and economical in manufacture.

The invention will be better understood from the description thereof to follow taken in connection with the accompanying drawing in which- Figure l is a side view partly in section of the improved apparatus.

Figure 2 is a top plan view thereof.

Figure 3 is a section on line 3-3 of Fig. 2.

Figure 4 is a fragmentary detail View of a filled capsule with its cap on.

The improved apparatus comprises a rectangular shaped metal base I9 provided with a pair of upstanding posts II at each end adjacent its sides. The edges of the upper longitudinal edges of the base are cut away as indicated at I2. At each end of the base between the posts I I a screw threaded opening I3 is provided; the opening at rone end having right hand screw threads and the opening at the other end having left hand screw threads. Mounted for upward and downward movements in each opening I3 is a screw threaded bolt I4. The bolts are threaded to conform to the threads in the openings. Each bolt has fastened thereto a knurled annular member I5 of sufficient diameter to permit a portion of its periphery to extend outside of the end of the base. A pin or lug I5 is formed on the upper surface of the annular member I5. The upper surface of the base is cut out around the openings I3 as indicated at I'I to receive the annular members I5 when at their lowermost position.

A capsule positioning plate I8 is removably mounted on the base. This plate is substantially the same size as the base and is provided with a plurality of holes I9 of any desired size or number. In the drawing, holes of two different sizes are illustrated. At each end of the plate and centrally thereof is a hole 20 and on each side of said hole 20 is a slot 2|. A groove 22 is pro- 1936, Serial No. 78,956

vided adjacent each longitudinal upper edge of the plate.

A slidable member or bar 23 is mounted on the plate. This bar has guiding and retaining feet or flanges 24 which are adapted to engage the lower surface of the plate. A set screw 25 holds the bar 23 in adjusted position.

In using the apparatus, the plate I 8 is mounted in position on the base so that the end openings 253 receive the lugs IB. When in this position the posts II extend upwardly through the slots 2i. The plate is thus mounted on the upper surface of the annular members I5.

When the number of capsules 26 desired to be lled is ascertained, the slidable bar 23 is slid along over the plate I8 until such a number of holes are exposed on one side of the bar. For example, if it is desired to fill 35 capsules, the bar 23 would be slid to the position shown in Fig. 2 thereby leaving 35 holes exposed on the left side of the bar. A capsule 26 is placed in each opening I9. The plate I8 is then elevated so that its upper surface is level with the upper edge of the capsules, such as is illustrated in Fig 3. This elevating is done by the fingers of the operator turning the annular members I5 so that the bolts I4 will rise in the openings I3 carrying the annular members and the positioning plate with them. A predetermined amount in Weight of powder is poured on to the plate and into the openings I9 and any excess powder on the plate can be brushed by a spatula or other tool into the openings. The grooves 22 at the sides receive the excess powder and prevent its falling over the sides of the plate. The bar 23 prevents any powder from being distributed on the other side thereof. A tamping tool may be used to tamp in the powder in the capsule. If desired the bar 23 may be slid over the openings I 3 to level off the powder in said openings. When the capsules are thus filled, the plate I8 is lowered by vturning the members I5 so that a portion of the upper end of the capsule is exposed above the upper surface of the plate I8 as is shown in Fig. 4. When the upper end of the capsule is thus exposed, its cap or complementary section 21 can readily be placed thereon. The plate I8 with the filled and capped capsules may be removed from the base and the capsules ejected from the holes in any desired manner.

The end grooves I2 permit the flanges or feet 24 of the sliding bar to move downwardly, and slots 28 formed on the edge of the plate I8 permit the removal of the bar from the plate without taking the plate off the base.

I claim:

1. A capsule lling apparatus comprising a base, a screw threaded bolt at each end of the base adapted for up and down movements, an annular member having a at upper surface fastened to the upper end of each bolt, a pin on the upper surface of said annular members, a plate having a plurality of capsule receiving holes and end holes, said plate being removably mounted on the annular members with its end holes receiving the pins, each of said annular members having a portion of its periphery extending beyond the ends of the base for convenience in turning the same and a sliding bar on the plate for indexing the capsule holes and levelling off the powder in the capsules.

2. A capsule lling apparatus comprising a base, a screw threaded bolt at each end of the base adapted for up and down movementa'an annular member having a flat upper surface fastened to the upper end of each bolt, a pin on the upper surface of said annular members, a pair of spaced guide posts on each end of the base, a plate having a plurality of capsule receiving holes, end positioning holes and guiding slots, said plate being movably and removably mounted on the annular members with its end holes receiving the pins and its` slots receiving the posts, each of said annular members having a portion of its periphery extending beyond the ends of the base for convenience in turning the same, a sliding bar on the plate for indexing the capsule holes and levelling 01T the powder and a set screw for holding said sliding bar in adjusted position.

3. A capsule iilling apparatus comprising a base, arscrew threaded bolt at each end of the base adapted for up and down movements, an

annular member having a flat upper surface fastened to the upper end of each bolt, a pin on the upper surface of each of said annular members, guide posts on the base, a plate having a plurality of capsule receiving holes, end positioning holes, guiding slots and longitudinal grooves, said plate being movably and removably mounted on the annular members with its end holes receiving the pins and its slots receiving the posts, each of said annular members having a portion of its periphery extending beyond the ends of the base for convenience in turning the same, a sliding bar on the Vplate for indexing the capsule holes and levelling off the powder, anges formed on said bar for engagement with the plate forguiding its movement and a set screw carried by said bar for holding it in adjusted position, said plate having slots for permitting the removal of the bar from the plate.
